It's very hard to recommend negative qualities, because we don't know your GM. He may be a sane and reasonable fellow. Or he may be an asshat that only GM's to powertrip over his players, and will screw you super hard no matter what you choose.
One can point out to your player(s) that they've invalidated the negative part of a negative quality, and still be the former GM type. It's like getting surgery for any of the multiple medical disabilities that can be taken as negative qualities, replacing / fixing buggy 'ware, or installing nanites when your system is nanite intolerant - the difference being that you have something left afterwards. A (somewhat empty) SIN. From the way you & A4BG responded, you'd think I suggested explicit hardline asshattery, when it was simply that it shouldn't be logged under 'negative qualities'.
Nearly everyone considers stuff like Form Fitting Body Armor ... to be discrete forms of protection, because that is the entire F-ing point of their existence.
Now you're just being a dick. PPP is explicitly available as discreet protection. FFBA is only discreet by virtue of being thin, custom-tailored and not extending beyond your other armour / clothing. And then some people just want the 6/2 armour.
If you're getting angry enough to start mock-swearing on forums over it, think about why. Come back with that, rather than this inane, "If you aren't doing X, you are a horrible, power-tripping, player-screwing GM". It's uncalled for.
